In this paper, we are concerned with the global wellposedness of 3-D inhomogeneous incompressible Navier-Stokes equations (1.2) in the critical Besov spaces with the norm of which are invariant by the scaling of the equations and under a nonlinear smallness condition on the isentropic critical Besov norm to the fluctuation of the initial density and the critical anisotropic Besov norm of the ho...

In this paper a general drift-flux model describing a subsonic and isentropic multi-phase fluid in connected pipes is considered. Each phase is assumed to be isentropic with its own sonic speed. The components are gamma-law gases with γ > 1. For such the computational challenge at a junction is the computation of rarefaction waves which do not have a readily available analytical form. Firstly, ...

In this two-parts paper, we present a systematic procedure to extend the known Hamiltonian model of ideal inviscid fluid flow on Riemannian manifolds in terms Lie–Poisson structures port-Hamiltonian Stokes-Dirac structures. The first novelty presented is inclusion non-zero energy exchange through, and within, spatial boundaries domain containing fluid. second that constructed as interconnection...

in the commercial banking activities, efficiency is an important issue for the bank managers, monitoring part and clients. this study has appraised the efficiency performance of the commercial banks in iran. the research method has been using windows data envelopment analysis with constant and variable returns to scale and input oriented model at the period of 1991-2006. the sample of study was...

Onsager's phenomenological equations successfully describe irreversible thermodynamic processes. They assume a symmetric coupling matrix between thermodynamic fluxes and forces. It is easily shown that the antisymmetric part of a coupling matrix does not contribute to dissipation. Therefore, entropy production is exclusively governed by the symmetric matrix even in the presence of antisymmetric...
